# Use `GetAuthorizationToken` with an AWS SDK or CLI
The following code examples show how to use `GetAuthorizationToken`.
Action examples are code excerpts from larger programs and must be run in context. You can see this action in context in the following code example:

#### [ CLI ]
**AWS CLI**
**To get an authorization token for your default registry**
The following `get-authorization-token` example command gets an authorization token for your default registry.
```
aws ecr get-authorization-token
```
Output:
```
{
"authorizationData": [
{
"authorizationToken": "QVdTOkN...",
"expiresAt": 1448875853.241,
"proxyEndpoint": "https://123456789012.dkr.ecr.us-west-2.amazonaws.com"
}
]
}
```

* @throws RuntimeException if there is an unexpected error during the operation.
